Fig. 7 1S adiametrical section, through the, same,sliow-' ing the inner s'ectionof the axle in elevation. Fig. 8 is a section taken vertically and dia- .1netrically of the steering frame, showing the 'steering'wheel in elevation. Fig. 9Qis' a similar section taken at right angles-to Fig. 8 and showing the steering wheel in rear elevation.

The main. frame of [the machine oom prises "the longitudinal bars I, 2; 3 and 4,

connectedv at the rforward end by a front I crossbar 5; extending. substantially I at right anglesxto the longitudinal b&i' S.'aIid"OH nected 'atthe" rear end by an oblique cross bar 6, while said longitudinal bars are conheated at a-plurality of other intermediate pointsbymeans of additional cross bars which'serve'zas the support for the; bearings I as shown at 7 'fin Fig.2? in order to provide ,for therelative[turning movement of the mam carrying traction wheels 8 which are mounted on the two. sections of'said' axle.

'of the various mechanicalelements hereinafterparticula'rly described. a 615 Adjacent to the forward portion of. the frame and beneath the same, isarrang'ed the I main axle 7, a portion ofwhich is tubular,

at opposite sides of the-main frame, as

7 shown in Fig.1. The-differential gearing,hy

meansof which thetw'o portions ofl 'the axle referred to' are connected, is best illustrated inFigs; 6 and 7 ,wherein it will be observed" that just inside of'oneof-the traction wheels '8 the solid section'7 of the axle has, mounted fast thereon abeveled gear wheel 9, while just opposite said wheel 9 is another'corres'ponding beveled. gear wheel 10', the hub of which is-i'ast on the tubular section"? of the main axle. Inter-posed between the .wheels 9 and 1Q is a seriesiof planetary pinions 11 which are mounted on stud axles projecting radially inwardfroma spur gear rim 12which meshes with and is actuated by a drivepinion 13, a's'shown .in'Fig. l,

the' pinion;' 13 being fast on a counter I shaft l l.

' The counter shaft l i'is provided with abeveled gear wheel 15 meshing with a bevlTwhicli impartsmotion to the rear steering traction wheel, as will-hereinafter appear. Adjacent to the gear wheel'15, theshaft 14 is equipped with difieren'tial gea-ring,'b est eledgear wheel'19v fast on said shaft while interposed between the wheels. 18 and l9 e'led pinion '16 on a longitudinal drive shaft illustrated in Figs. 3 and 4, and shown as comprising a beveled gear wheellS- loose .onthe counter shaft'14 and a similar 'bevis'a' plurality of planetary .pinions 20-:mounti ed onthe inner side of a s u'r gear rim 2lpinion 22 on a'transmission shaft 23'. v I

Mounted on'the forward portion of the frame and extending partially over the main shaft '7 is a motor 24, shown as ofthe ordi-i nary four-cylinder internal combustion'type, the shaft of which is shown as provided at one" 'which meshes with and is riven by a. spur end. with afly wheel 25, while the other shaft is provided with a beveled gear wheel 26 which meshes with oppositely arranged twin beveled gear Wheels 27 and 28. The wheels 27 and 28 are both loose on the shaft 23, but either one of said wheels-is adapted tobe locked to the shaft 23 b .means of a clutch, as shown in Fig. 51 cm odying a sleeve 29 keyed to the shaft, as shown at '30, and provided at opposite ends with clutch heads 31 and 32 movable into and out of corre-. vsponding recesses 33 and 34in the wheels 27 and 28, respectively. Centrally the sleeve is provided with a. roove 35 in which works the fork 36 of a c utch lever 37 'fulcr'um'ed.

on the machine frame and provided with a thumb latch 38 adapted to interlock with I cal axes in brackets projectin a rack segment 39, whereby either clutch head may be moved into engagement with the respective-gear 27 or 28 and locked, the gearing thus describedbeing adapted for the purpose of driving the machine forward or backward, as may be desired.

Adjacent to the rear ortion ofthe ,main frame-of the machine is ere is provided an annular oscillator frame 40 which moves between guide rol ers 41 journaled on vertif'rom adjacent frame bars, the said annu ar fra'me also working betwee'nother supporting rollers' 42 arranged above and beneath the annular frame and jjournaled on horizontal axes in I other brackets .connected with'the machine frame. Extending downward from the frame is a fork 43 carrying an axle 44 .on

which is mounted a traction steering .wheel 45, the same bein driven by means of a sprocket wheel 46 aving a fixed relation to the traction wheel 45, around which passes a'sprocket chain 47 which extends upward through the annular frame 40 and passes around a' driving sprocket wheel48 fast .on a tumbling shaft 49, one portion of which is journaled in'brackets 50 carried by the an-. nular frame 40, while the other 4 portion thereof is journaled in brackets 51 mounted on the main frame of the machine. The

v tumbling shaft 49 is provided with a tumpecial y valuable in propelling the machine.

around short turns or curves.

The steering mechanism embodies a shaft 55' which extends transversely of the machine frame, as shown in Fig. 1,Aand is provided with steeringchains 56 and 57 which arewraipped opposite directions around t 55,- as indicated in Fig; 1,' the ends of said-chains being connected to the annuthe sha lar frame- 40 v at 1dia metrical1y opposite points. .--On-' one end of the shaft 55 is mounted fast a worm wheel 58 which meshes -with and is actuated 'by'aworm 59 on a steering post 60 provided with a hand wheel 61within.reach of the motorman', who by Y .turning said wheel 61 may im art ajcorresponding movement to the s aft 55 to wind or-un'wihd the chains 56 and 57 and turn the frame 40, correspondingly turning the steering wheel-f 45. The tumbling joint 52v allows o r such turning of'the steering wheel without affecting the driving mechanism by which rotary motion is imparted to the wheel 45 for propelling the machine. In rear of the oblique cross bars 6 and parallel therewith is arranged a plow-lifting bar 62 which 1s connectedto all of the beams 63 of the plow, 64 by means of bolts 65 which are connected at their .upper ends to the liftin bar 62, while thelower portions of said bo ts pass through guides 66 on the plow beams 63, as shown in Fig. 2, thus allowing for a limited u and down movement of the 68 to a draw bar 69 arranged arallel to the lifting bar 62 and connected y draft rods '70 .to the main frame of the machine, said draft rods being shown-as pivotally connect-e ed at 71 to brackets 72 secured to the underside of the main frame, see Fig. '2.

IncIining upwardly. and rear-wardly from the main frame and fastened to said frame are supporting bars 73 carrying at their rear ends rollers 74 around which pass lifting connections 75 havingt h eir ends connected.

by means of eye-bolts 7 6, ortheir equivalent,

to the lifting bar 62. 'After passing over the pulleys or rollers 74, the connections 7 5 over direction pulleys 78 on the -machine frame, the connections! 5 being-then wound upon a drum 7 9 journ'aled on the machine frame and having fast thereto a ratchet wheel 80 with which engages a pawl or detent 81 connected by means of a rod 82 with a foot lever 83, by means of which the pawl 81 may be thrown out of engagement with the ratchet wheel 80 to release the tension on the connections 75 for the purpose of lowering the plows 64. a I i In order to provide for lifting the plows, the shaft of the drum.7 9 is provided with a friction wheel 84 movable into and out of pass under other pulleys 77 on the upper side of the draw bar 69 and thence upward who may thus readily shift. the wheel 8st into engagement with the wheel 85 and thereby utilize the power of theengine for turning the drum 79 and winding up the connections 7 5 to raise the plows (Ea-to any desired degree. In moving the machine fromplace to place, the connections .75 will be woundup sufliciently to elevate the plows -to a point'where they will clear-the ground. It will be noted that the first eflect of winding up the connections 75 is toraise the points of the. plows by first elevating the draw bar 69. This causes the plows to automatically ride out of the ground,point first. The first effect of releasing the connections 7 5 is to lower the draw bar 69, thereby causing the points of the plows to dip downward and enter the-soil.

It will be understood that the invention hereinabove described is adapted for use in connection with a steam engine in lieu of only change necessary being to mountan upright reversely on the steam engine in place of the gears 26, 27 and 28 and place the pinion 22 on the shaft of the steam engine. The engine boiler may be placed at the-front of the machine andmay' be either an upright, tubular or'water tube boiler while the lifter action may be worked by arranging the friction wheel 84 so that it may be moved into and out of contact with a similar wheel on the engine shaft.
